Comparison of triple antibiotic paste removal by different irrigation techniques.

Abstract

This study compared different irrigation techniques in triple antibiotic paste (TAP) removal from root canals. Fifty-six maxillaryanterior-teeth were filled with TAP for 28 days, and assigned into 5 experimental groups (n=10): Syringe irrigation (SI), NaviTip FX (NFX), Vibringe-Syringe irrigation (V-SI), NaviTip FX-Vibringe (V-NFX), passive ultrasonic irrigation (PUI) and positive and negative control groups (n=3 for each). Following the removal of the medicament, the remaining medicament was evaluated using 4-grade scoring-system. V-NFX and NFX showed similar performances (p>0.05) while V-NFX was significantly more efficient than SI and PUI (p<0.05) at all parts of root canals. VSI was less efficient at apical part when compared to NFX and V-NFX (p<0.05) while not significantly different from PUI and SI at all parts of the root canals (p>0.05). Regarding different parts of the root canals, V-SI and PUI were significantly less efficient at the apical part (p<0.05). In conclusion, the brush form of irrigation delivery with and without sonic activation improved the removal of TAP from the root canals when compared to ultrasonic activation, syringe irrigation or sonic activation alone.
